Abstract

Background

The purpose of our study was to investigate some correlation between tumor and microenvironment infiltration of CD8(+) T-cells, eosinophils and neutrophils, clinical parameters, treatment options and OS in our patient cohort.

Methods

In the prospective study we analyzed cards and tumor samples of 15 patients with colorectal and gastric cancer: 6 patients with gastric cancer: 2pp. - stage II; 4pp. - stage IV; 9 patients with CRC: 5pp. - stage III, 4pp. - stage IV. All patients were treated under the standard clinical complex protocol. All patients were under our supervision from 2013 to 2015. We studied clinical stage, level of expression of CD8(+) T-cells, eosinophils and neutrophils in the tumor and microenvironment.
